Original change's description:
> Draw image filters directly under non-axis-aligned transforms
>
> This removes hacking the canvas CTM and wrapping the paint's image
> filter in a special MatrixTransform that computed a post-transform
> instead of its documented pre-transform effect. Performance-wise, the
> computed layer sizes should be about the same, but we avoid one less
> render target switch because we apply the transformation while drawing
> to the dst device, vs. transforming into another temporary layer and
> then drawing that to the dst device.
>
> Several important changes in behavior here:
> 1. The DeviceCM record no longer has a stashed matrix to restore and
> holds its restoration paint directly.
> 2. Devices for image filter inputs can now have device-to-global
> transforms that are not integer translates.
> 3. The MatrixTransform hack punted when there was perspective because it
> could produce excessively large temporary images, but the new version
> appears to work around that. We now impose a maximum layer size to
> protect against that and automatically scale the layer to prevent it.
> Perspective image filters otherwise now draw correctly.
> 6. Updated layer sizing code to use the new image filter APIs
> 7. Updated backdrop filter and restore filters to go through the same
> code paths, although restore filters skip the intermediate image
> transform.
> - layer bounds and transforms now go through the updated skif API
> and is hopefully more straight forward to understand.
> 8. Now we can optimize root color filter nodes of a filter DAG, even if
> the entire DAG can't be represented as a color filter. The last node
> is pulled off and composed with the restoration paint instead.
